Block Jump Height Assessment Based on Kinetic Approach in Volleyball Players: Is There any Difference Between Methods?

Purpose: Various kinematics and kinetics methods have been proposed for the assessment of jumping ability as a critical skill in professional volleyball players, but little is known about the accuracy and differences between these methods. Therefore, the objective of the current study was to answer the question “Is there any difference between the results of various kinetic methods in the assessment of block jump height in volleyball players or not?” Methods: Twenty-one healthy male junior volleyball players of the Iran national team performed the block jump task on a force platform. Three common formulas mostly used in literature based on kinetics output of force platform were selected for the comparison of resultant jump height. Descriptive analysis, Shapiro-Wilk test, and ANOVA were used for statistical calculations (p
